Notes
1) Motoactv behaved well today, giving a distance of 4.25 miles for the UNCC greenway route (Google Maps gives 4.34 miles, which would have given me a pace of 7:36). 0.09 miles off is not too bad.
2) I exported data from the Motoactv website in the TCX format (new option!), and this worked very well. TCX format saves the interval data, so I can see my mile splits.
